The phones in the Raiders’ draft room have been ringing in symphony for two days and nights straight now. Two trades during the first round of the NFL Draft on Thursday, three more trades to get three players in the second and third rounds Friday.

Raiders coach Jon Gruden’s cell phone joined in all the noise on Friday night.

“My mom called me and asked if Mr. Davis was making these picks from heaven,” Gruden said, smiling.

Al Davis, the late owner who hired Gruden for the first time here 20 years ago, would have loved Martavis Bryant, the deep threat acquired from the Steelers Thursday. And he would have been excited about LSU pass rusher Arden Key, the team’s second third-round pick on Friday.

Key was only available at No. 87 (the Raiders traded up two spots to get him) because he has been in rehab, and has been suspended both at LSU and in high school.
